Description

[0001] The invention relates to a wet cell structure according to the preamble of claim 1.

[0002] In the field of construction engineering, the construction of buildings involves the constant logistical effort of planning and coordinating diverse work processes for a multitude of different trades. This creates a series of interdependencies between individual work steps, meaning that a delay in one specific trade often leads to a postponement of other dependent work steps, significantly increasing both the construction time and the building costs. This represents an inherent risk in every construction project.

[0003] To avoid and circumvent such dependencies and delays, a number of construction techniques have been developed over time. A significant step in this direction was the introduction of prefabricated construction, in which individual modules of a building are prefabricated and assembled on the construction site. This significantly reduced construction time and, through the mass production of individual modules, also enabled a reduction in construction costs.

[0004] However, even with modern construction techniques, after the building envelope has been erected, it is necessary to coordinate a large number of different trades during the interior finishing.

[0005] Wet areas, such as toilets, bathrooms, and large showers, represent a significant cost and time factor in the construction of modern buildings, as they involve extensive installation and sealing work. Furthermore, high-quality workmanship, particularly regarding the waterproofing, is essential in wet areas, since faulty sealing can lead to extensive consequential damage to the building. This requires, in some cases, substrate preparation, the extensive use of construction chemicals directly on site, and adherence to drying times between different work steps. The installation and laying of tiles, flooring, and wall coverings also demand considerable time and skilled, professional personnel. Therefore, the construction of wet areas is both a costly and time-consuming building project with a high potential for errors.

[0006] The object of the present invention is to provide a wet cell design which avoids these disadvantages of the prior art.

[0007] According to the invention, this problem is solved by a wet cell assembly comprising a floor element and at least one wall element connectable to the floor element, wherein the floor element comprises a floor element frame and the wall element comprises a wall element frame. According to the invention, the wall element frame is designed for connection to the floor element frame along a lower edge of the wall element frame. The floor element and the wall element each further comprise a sealing plane, wherein the respective sealing plane seals an inner side of the floor element and an inner side of the wall element, at least partially, preferably substantially completely, in a liquid-tight manner. Furthermore, according to the invention, the floor element comprises a floor covering arranged on the inner side of the floor element, and the wall element comprises a wall cladding arranged on the inner side of the wall element.

[0008] This offers the advantage that the entire wet room structure can be prefabricated, eliminating the need for time-consuming installation of flooring and wall coverings on the construction site. Furthermore, the wet room structure is manufactured in a fully modular fashion, allowing it to be either fully assembled on-site or requiring only the floor and wall elements to be connected. The pre-installed waterproofing eliminates the need for extensive sealing work on-site, resulting in significant cost and time savings. Additionally, prefabrication of the wet room structure allows for the implementation of quality control mechanisms that would be impossible with conventional on-site wet room manufacturing.

[0009] Preferably, the floor covering and / or the wall cladding of the wet room structure according to the invention are made of a ceramic material. The use of the wall element frame and the floor element frame offers the advantage that the wall and floor cladding, even if they consist of large-area ceramic elements, can be installed quickly and easily, and in particular without time-consuming leveling work on site.

[0010] According to the preferred embodiment of the wet room assembly according to the invention, the floor covering and / or the wall cladding have a sealing membrane arranged on the back side of the floor covering and / or on the back side of the wall cladding, the sealing membrane forming the sealing layer. This achieves the advantage that the sealing layer is created simultaneously with the installation of the floor covering or the wall cladding. This reduces the time required for the production of the floor and wall elements of the wet room assembly according to the invention. Preferably, the floor covering is bonded directly to the floor element frame. Furthermore, the wall cladding can also be bonded directly to the wall element frame.This achieves the advantage that a ceramic composite wall panel can be used for wall cladding, which does not require any carrier material, and no construction chemicals need to be used on the construction site during the installation of the wet room structure according to the invention.

[0011] According to the preferred embodiment of the wet room assembly according to the invention, the wall element and / or the floor element comprises at least one connection pipe for a wet room fitting or a drain penetration, wherein the wall cladding and / or the floor covering includes at least one recess for the passage of the connection pipe for the wet room fitting or for the drain penetration. This achieves the advantage that no cutting work is necessary on the construction site to route pipes or other building installations through the wall cladding or the floor covering.

[0012] According to the preferred embodiment of the wet cell structure according to the invention, the floor element frame and / or the wall element frame are made essentially entirely of metal profiles. This enables rapid and cost-effective manufacturing of the floor element frame and the wall element frame, while simultaneously achieving high strength and mechanical stability.

[0013] Preferably, the floor element frame is also filled with a filling material, preferably comprising concrete, screed, and / or leveling compound. This provides additional stabilization to the floor element. Furthermore, the floor element frame can include underfloor heating pipes embedded in the filling material.

[0014] Preferably, the floor element frame and / or the wall element frame each comprise at least one reinforcing strut, preferably made of a metal profile. This further improves the mechanical stability of the floor element frame or the wall element frame.

Figure 6c shows a section of a sectional view of the floor element of the wet room structure according to the invention in an embodiment with a wastewater pipe received by the floor element.

[0016] A wet cell structure 1 according to the invention comprises a [unclear] in the Figures 1a to 1c visible floor element 2 and at least one wall element 3 connectable to the floor element 2, which is located in the Figures 2a and 2b This is evident. The floor element 2 comprises a floor element frame 4, and the wall element 3 comprises a wall element frame 5.

[0017] According to the invention, the wall element frame 5 is designed for connection to the floor element frame 4 along a lower edge 6 of the wall element frame 5. The floor element frame 4 and the wall element frame 5 can be joined, for example, by riveting, screwing, welding, or similar methods. Further connection methods will be apparent to those skilled in the art from this exemplary reference. The wet cell assembly 1 is in its assembled state in the Figures 3a to 3cThe floor element 2 and the wall element 3 each further comprise a sealing plane, not shown separately in the figures, wherein the respective sealing plane seals an inner side 7 of the floor element 2 and an inner side 7 of the wall element 3 at least partially, preferably substantially completely, in a liquid-tight manner. The inner side 7 is the side facing the interior of the wet cell. Furthermore, according to the invention, the floor element 2 comprises a floor covering arranged on the inner side 7 of the floor element, not shown separately in the figures, and the wall element 3 comprises a wall cladding 8 arranged on the inner side 7 of the wall element 3, which in Figure 4 is shown.

[0018] The design of the wet cell assembly 1 according to the invention offers the advantage that the wet cell assembly 1 can be completely prefabricated, for example, in a factory or production hall, thus eliminating the need for time-consuming installation work of floor coverings and wall coverings 8 on the construction site. Furthermore, the wet cell assembly is manufactured in a completely modular fashion, allowing it to be either fully assembled and delivered to the construction site or for the floor element 2 and the wall element 3 to simply be connected. The sealing layer also eliminates the need for complex sealing work on the construction site, resulting in significant cost and time savings. In addition, the prefabrication of the wet cell assembly 1 makes it possible to implement quality control mechanisms that would not be feasible with conventional on-site manufacturing of a wet cell.The wall element 3, or wall elements 3 if several wall elements 3 are connected to a floor element 2 to form a wet room structure 1 according to the invention, can also be manufactured in different widths or thicknesses. These include, for example, 75 mm and 35 mm. Furthermore, wall elements 3 can be manufactured such that all pipe penetrations can be installed in the respective wall profile 3, preferably with a width or thickness of 75 mm for the wall profile 3.

[0019] According to the preferred embodiment of the wet cell assembly 1 according to the invention, the floor covering and / or the wall cladding 8 are made of a ceramic material. The use of the wall element frame 5 and the floor element frame 4 offers the advantage that the wall cladding 8 and the floor cladding, even if they consist of large-area ceramic elements, can be installed quickly and easily, and in particular without complex leveling, laying, or gluing work on site.

[0020] According to the preferred embodiment of the wet room assembly 1 according to the invention, the floor covering and / or the wall cladding 8 also have a sealing film arranged on the back side of the floor covering and / or on the back side of the wall cladding 8, which is not visible in the figures. The sealing film preferably forms the sealing layer. This has the advantage that the sealing layer is created simultaneously with the installation of the floor covering or the wall cladding 8. This reduces the time required for the production of the floor element and the wall element 8 of the wet room assembly 1 according to the invention.

[0021] Preferably, the floor covering is bonded directly to the floor element frame 4. Furthermore, the wall cladding 8 can also be bonded directly to the wall element frame 5. This offers the advantage that a ceramic composite wall panel can be used for the wall cladding 8, which requires no carrier material, and no construction chemicals need to be used on-site during the installation of the wet room assembly 1 according to the invention. Moreover, according to the preferred embodiment of the wet room assembly 1 according to the invention, a structural unit is formed by the connection between the floor element 2 and the wall element 3, as well as between the floor covering and the wall cladding 8, which are made of ceramic material.

[0022] According to the preferred embodiment of the wet cell assembly 1 according to the invention, the wall element 3 and / or the floor element 2 comprises at least one connection line 9 for a wet cell fitting or a drain opening 10. This is, for example, Figure 2a The wall cladding 8 and / or the floor covering comprise, according to this design variant, as shown in Figure 4 shown, in addition at least one recess 11 for the routing of the connecting line 9 for the wet room fitting or for the drain penetration 10. This achieves the advantage that no milling or cutting work, as well as generally no additional adjustments, are necessary on the construction site to route pipes or other building installations through the wall cladding 8 or the floor covering.

[0023] According to the preferred embodiment of the wet cell assembly 1 according to the invention, the floor element frame 4 and / or the wall element frame 5, as shown in the figures, are made essentially entirely of metal profiles. This enables rapid and cost-effective production of the floor element frame 4 and the wall element frame 5, while simultaneously achieving high strength and mechanical stability. Preferably, the floor element frame 4 is also filled with a filler material, preferably comprising concrete, screed, and / or leveling compound, which is not shown in the figures. This further stabilizes the floor element 2. Furthermore, the floor element frame 4 can include underfloor heating pipes embedded in the filler material, which are not shown separately in the figures.

[0024] During the filling of the base element frame 4 with filler material, a template or relief profile (not shown separately in the figures) is preferably used and placed on a substrate. This relief profile or template has a shape that corresponds to a negative impression of the desired surface of the base element 2. Thus, the relief profile includes, for example, projections and slopes whose negative impression corresponds to a recess for a shower tray and / or a slope to ensure water drainage. Subsequently, a sealing membrane is applied to the relief profile or template, forming the sealing layer. The base element 2 has, as shown in Figures 1b and 1cAs shown in a preferred embodiment, a formwork frame 14 is erected, which may preferably be integral with the floor element frame 4 and connects to the inner side 7 of the floor element. The floor element 2 is then placed over the template and the sealing membrane arranged thereon, with the inner side 7 facing downwards, i.e., with the inner side 7 facing the relief profile or template. Subsequently, the floor element is at least partially filled with the filler material, the formwork frame 14 ensuring that the filler material remains within the floor element 2 and does not leak out. Preferably, before the filling step, components of an underfloor heating system, such as heating pipes, can also be arranged within the floor element 2 or within the floor element frame 4, and these are also encased in the filler material.Following the filling step with the filler material, preferably after a certain drying or curing time, the base element 2 is turned over and the relief profile or template is removed. This creates a surface structure on the base element 2 in which, for example, recesses for shower trays, slopes for water drains or similar features are already present, and simultaneously establishes the sealing surface.

[0025] Preferably, the floor element frame 4 and / or the wall element frame 5 each comprise at least one reinforcing strut 12, preferably made of a metal profile. This further improves the mechanical stability of the floor element frame 4 and the wall element frame 5, respectively. Figures 2a and 3a One variant of the wall element frame 5 is shown, which includes reinforcing struts 12.

[0026] Figures 5a to 5d show a further embodiment of the wall element 3 of the wet room assembly 1 according to the invention, which includes an additional recess 13 for a door, such as a sliding door. This embodiment is also shown in the wet room assembly 1 according to the Figures 3a to 3c used, in which a complete wet room assembly 1 with four wall elements 3 is shown, which form the four walls of the wet room. In the Figures 3a to 3c However, the wet room structure 1 is shown without floor covering and without wall coverings 8. Figure 3c Figure 1 shows the wet cell structure according to the invention installed in a building floor, in which the floor and the building services lines are also visible.

[0027] Figure 6aFigure 1 shows a corner section of the base element 2 according to one embodiment, in which at least one additional anchoring point 15 for the filling material is provided. According to the embodiment shown in Figure 2 Figure 6a Two anchoring points 15 for the filling material are provided for each corner of the floor element 2, with additional anchoring points 15 being provided along each of the edges of the floor element 2. Figure 6bFigure 1 also shows a corner section of the floor element 2 in another embodiment, which also features the anchoring points 15. After the floor element 2 has been filled with fill material, the anchoring points 15 can be used to fix the fill material within the floor element 2. Furthermore, when the floor element 2 is lifted, the forces acting upon it are transferred directly to the floor element frame 4, thus preventing twisting or bending of the components of the wet room assembly 1 and ensuring that no forces are transferred directly to the wall elements 3. The anchoring points 15 can either be integrated directly into the floor element frame 4 or, for example, be formed from separate metal profiles that are screwed, riveted, or welded to the floor element frame. This also provides additional corner stiffening of the floor element 2.In addition, the base element 2, together with any wall elements 3 connected to the base element 2, can be lifted at the anchoring points 15 before being grouted with the filling material.

[0028] As in the Figures 6a and 6b As shown, the floor element 2 can also have additional lifting points 16. These lifting points 16 can be used to lift and manipulate the floor element 2. Furthermore, these lifting points 16 can also be used as anchoring points 16 to anchor the floor element 2 to a floor slab. In this case, the floor element 2 can be screwed to the floor slab using the lifting points 16 or the anchoring points 16.

[0029] Figure 6cFigure 1 shows a partial cross-section through the base element 2 according to one embodiment, in which the base element 2 includes an additional base profile 17 designed to accommodate a wastewater pipe 18, at least in part. This achieves the advantage that no additional installation space needs to be provided for the wastewater pipe. The base element 2 is preferably designed such that wastewater pipes 18 with a diameter of DN90 mm can be fully integrated into the base element 2 without any loss of space. The base element frame 4 can be bent inwards to preserve the necessary space.
